Burglar-proof doors protect you from unpleasant burglary situations and the associated consequences. Take important security precautions in the area of the apartment entrance door so that you are protected from burglars even when you are away.
What’s a burglary?
A burglary is the unauthorised entry into a delimited area when an obstacle is overcome. What is considered an obstacle is defined in the applicable law. A burglary usually occurs with the aim of gaining possession of objects and/or information.
A burglary in one’s own four walls is a big shock for many people, young and old. However, the violation of privacy, the lost sense of security or even serious psychological consequences that can occur after a break-in often cause more trouble than the purely material damage.
Protect against burglary with security doors
Burglar-resistant doors are used where unauthorised forced entry into a room or area to be protected is to be made more difficult or impeded. Crime statistics show burglary and theft offences at an alarmingly high level. Effective defensive or delaying measures against violent house and apartment burglaries are extremely important. Especially the occasional burglaries, in which burglars use few tools during the day to break into homes, are almost exclusively due to the inadequate protection provided by the doors.
To protect your doors effectively against burglary, we recommend the following measures:
- Only use tested burglar-resistant house and apartment entrance doors.
- Always lock twice when leaving the apartment.
- Never hide the apartment key from the front door, burglars know the hiding places.
- If a key is lost, the locking cylinder should be replaced.
- Do not leave keys inserted from the inside, this is especially true for doors with glass panels.
- Use door viewers and locking bars, a healthy distrust of strangers is advisable.
Requirements for burglar-resistant doors
Tested burglar-resistant doors are intended to force the perpetrator to stop the attempted break-in after a certain period of time. Security doors achieve their burglary resistance through reinforced door leaf constructions, reinforced fittings (hinges, locks, strike plates) as well as burglar-resistant protective fittings and profile cylinders. Furthermore the professional installation of the door element plays a decisive role. Other components, such as door viewers, bolt switch contacts and self-locking locks, optionally provide additional security.
Inspection of the door elements
The burglar-resistant elements specially developed by the door manufacturer are subjected to various static and dynamic tests on the test stand. Special internal layers, hinges, hinge holders, locks and striking plates ensure that the door element withstands the burglary tests in the locked state for a defined period of time. Physical force as well as various tools are used for this purpose.
Resist without putting yourself in danger. Depending on the resistance class, different tool sets are used to break open the door leaf. Each resistance class also increases the resistance time, i.e. the time available to the burglar to open the door. Furthermore, a correct installation of the door element is absolutely necessary to pass the test. After passing the test, the tested components are permanently marked by the door manufacturer with a sign.
After successful testing of the burglar-resistant door element, the door manufacturer is issued with the test certificate and may mark the tested door with the resistance class RC1 – RC6.
Recommendations for use of burglar-proof doors
For approximate orientation, which resistance class is useful for which location, you will find an overview below. Nevertheless, expert advice (for example from the local police advice centres) is essential. The assessment of the risk should be carried out at your own responsibility, taking into account the location of the building (protected, unprotected), use and material assets. If the risk is high, additional tested and certified burglar alarm systems should be used.
